ISOTHERMAL CALORIMETRY - 6

Precise Temperature Control and Industry-Proven Performance The TAM Air is an air-based thermostat, utilizing a heat sink to conduct the heat away from the sample and effectively minimize outside temperature effects. The calorimeter channels are grouped in a single removable block. The thermostat uses circulating air and an advanced regulating system to keep the temperature stable within ±0.02 °C. The high accuracy and stability of the thermostat makes the calorimeter well-suited for heat flow measurements over extended periods of time, e.g. weeks. TAM Air Thermostat Features and Benefits:...

ISOTHERMAL CALORIMETRY - 7

TAM AIR TECHNOLOGY Versatile and Robust Calorimeter Performance The TAM Air calorimeter block is available in two versions, both employing twin-type calorimeters. The 3-channel large volume calorimeter block has three twin-type calorimeters that can accommodate 3 samples of up to 125 mL volume. The 8-channel standard volume calorimeter can accommodate eight samples of up to 20 mL volume. In both calorimeter blocks, all the samples can be measured simultaneously and independently of each other. The only characteristic of each experiment in common is the thermostat temperature. The...

ADMIX AMPOULE Sample Handling System – Admix Ampoule Stirring motor The Admix ampoule is a 20 mL accessory available for the 8-channel standard volume calorimeter. It is used for initiating reactions inside the calorimeter, and can be used for Manual stirring control monitoring a reaction from the initial injection. The Admix Ampoule can be configured with or without a motor for stirring. For samples such as mixtures of cement and water, manual stirring is recommended. For liquid systems, a motor may be used for stirring. The Admix Ampoule can only be used with 20 mL disposable glass...

MODULE 614S14 PuuP COHTUt* TAM AIR/ACCESSORIES Calorimetry is a non-specific technique as it measures everything that is occurring in the sample. To increase the specificity of a calorimetric measurement it is possible to add a probe to connect a chosen property to the heat flow signal. A user-configured probe can be connected to the Voltage In/Out module of the Accessory interface box to log the voltage measured simultaneously with the calorimetric data. Features: • Increased specificity of the measurement. • Up to eight (8) identical or different accessories connected and controlled thru...
